Aspiration BIM definition in 5yrs
Standard processes and information classification to develop and manage both geometrical and non‐geometric digital information of a facility
Goal: to enable better coordination, extended analysis and enhanced communication amongst the supply chain resulting in efficiency gain in construction time, quality and cost.

Evaluation of BIM status in Qatar
• Data sources• Primary: 28 semi‐structured interviews• Secondary: Literature, PWA GCC, AEB BIM execution plan, HOCHTIEF ViCon services agreements, Qatar University BIM model exchange process map
• Questionnaire design• Policy, People, Process, Technology questions• 18 questions with 36 subtopics• 45 min each interview
• Frequency analysis
